Abstract: PROBLEM TO BE SOLVED: To provide a blower that obtains high-accuracy air flow/static pressure characteristics having extremely little variation of air flow even if static pressure, such as pressure loss, is varied, in addition that increase a blast volume according to variation of humidity when the humidity is high.SOLUTION: A magnetic pole of a magnet rotor 3 is formed of a polyamide 6 resin, which has many amide groups in the same molecular length, and therefore a water molecule forming a hydrogen bond with the amide groups makes the surrounding water molecules come near within a region having much higher humidity to form a hydrogen bonding between the water molecules and swell. Accordingly, the outer diameter of the magnetic pole of the magnet rotor 3 is increased, an air gap 18 is decreased, and then an induced voltage induced by a drive coil 2 is increased. In addition, if a current supplied to the drive coil 2 is the same, shaft torque is increased by the amount of increased induced voltage. As a result, the air flow/static pressure characteristics are obtained in which ventilation air flow is increased at high humidity compared with that at normal humidity.
